I have a regular life insurance a small portion of which could be used to buy a cryonic burial (there are ways to get an advance on one's life insurance while you are still kicking) should I want one.

I have guesstimated the odds of the eventuality where a preexisting cryo coverage would be better than buying it when actually needed, and they seem very low:

• any disease or accident resulting in brain damage renders cryo useless
• any accident resulting in quick death renders cryo useless
• any situation where end of life is not immediate but expected within a short time frame (e.g. aggressive incurable disease) without affecting mental faculties leave time to make cryonic arrangement through savings or existing insurance if desired.

The only reason I see to buy cryo insurance is more of an altruistic nature: to financially support a cryobank before I need their services so that they can freeze some of those who cannot afford it.

There is also the potential issue of their business model relying on people paying for but not being able to use the coverage, but if they actually do that, I cannot expect them to last long enough to attempt a successful revival.
